Retail Media Networks in 2026: Amazon DSP vs. Criteo Commerce Max

Retail media has become the fastest-growing ad channel in e-commerce, with U.S. retail media network spending projected to hit $61.4 billion in 2026, according to eMarketer’s June 2026 forecast. At the center of that arms race are two platforms with fundamentally different philosophies: Amazon DSP, the walled-garden behemoth with unmatched purchase-intent data, and Criteo Commerce Max, the open-internet challenger that aggregates first-party data across hundreds of retailer partners. For Shopify sellers running off-Amazon acquisition, DTC brands scaling paid media, and agency leaders building cross-channel programs, the choice between these two platforms is one of the most consequential budget decisions of 2026.

What is the core difference between Amazon DSP and Criteo Commerce Max?

Amazon DSP is Amazon’s demand-side platform, giving advertisers programmatic access to Amazon-owned inventory — including Amazon.com, IMDb, Twitch, and Freevee — plus third-party publisher inventory powered by Amazon’s shopping signal graph. The platform’s core advantage is its closed-loop attribution: because Amazon owns both the ad surface and the transaction layer, ROAS measurement is unusually clean for products sold on Amazon. As of Q1 2026, Amazon Advertising’s total revenue hit $15.3 billion for the quarter, up 19% year-over-year, with DSP representing a growing slice of that pie as brands move beyond Sponsored Products.

Criteo Commerce Max, rebranded from its older retargeting roots, operates differently. It stitches together first-party shopper data from over 225 retailer partners — including Macy’s, Costco, Target, Carrefour, and Kroger — to serve ads across the open web, connected TV, and in-store digital screens. Criteo’s Commerce Media Platform processed $900 billion in annual e-commerce transactions in 2025, giving it a cross-retailer signal footprint that no single DSP outside of Amazon can match. Revenue for Criteo’s Commerce Media segment grew 18% year-over-year in Q4 2025 to $542 million.

“Amazon DSP is the right answer if you’re optimizing for Amazon conversion. But if your growth strategy lives outside Amazon — on Shopify, at Walmart, at specialty retail — Criteo Commerce Max is giving us attribution fidelity we didn’t think was possible on the open web.” — Dana Kwon, VP of Performance Marketing at Caden Supply Co., a $40M DTC home goods brand

How does targeting and audience data compare between the two platforms?

Amazon DSP’s audiences are built on real shopping behavior: search queries, product page views, purchase history, and Subscribe & Save data across Amazon’s U.S. base of 167 million Prime members. Advertisers can target in-market segments like “Browsed Baby Gear in Last 30 Days” or “Purchased Competitor Brand in Last 90 Days” with a specificity that third-party data providers can’t replicate. Amazon also launched its AI-powered audience expansion tool, Audience Discovery, in March 2026, which uses large language models to identify lookalike cohorts from behavioral embeddings rather than simple demographic proxies.

Criteo Commerce Max takes a federated approach. Retailer partners share anonymized, hashed first-party data into Criteo’s Commerce Grid identity spine, which the platform claims matches 725 million shopper profiles globally. Because the data is contributed by over 225 retailers, Criteo can serve relevant ads to shoppers who have never visited Amazon — a meaningful capability for brands distributed through specialty retail, wholesale, or their own Shopify storefronts. Criteo’s AI Engine, updated in Q1 2026, now optimizes bids across retailer audiences in real time using a multi-armed bandit model that adjusts allocation every six hours based on marginal ROAS signals.

• Amazon DSP strengths: Prime member purchase data, closed-loop attribution for Amazon SKUs, Streaming TV inventory at scale, AMC (Amazon Marketing Cloud) for custom SQL analysis
• Criteo Commerce Max strengths: Cross-retailer shopper graph, open-web reach, CTV + in-store digital inventory, works for brands not sold on Amazon
• Amazon DSP weaknesses: Attribution breaks down for off-Amazon sales, minimum spend thresholds ($35K/month managed service), limited transparency into bid logic
• Criteo Commerce Max weaknesses: Smaller premium publisher footprint than Amazon’s owned inventory, retailer data quality varies by partner, UI requires significant ramp time

What do minimum spends and platform access look like in 2026?

Amazon DSP remains a high-commitment entry. Managed service requires a minimum of $35,000 per month, making it inaccessible for most small sellers. Amazon has pushed its self-service DSP interface harder in 2025 and 2026, lowering the technical barrier, but self-service still requires an active Seller Central or Vendor Central account and meaningful existing advertising history to get clean ASIN-level attribution. For agencies, Amazon DSP certification has become a table-stakes credential, with Amazon’s APS (Amazon Partner Network) requiring annual recertification as of January 2026.

Criteo Commerce Max operates on a more flexible tiered model. Brands spending as little as $10,000 per month can access self-service tooling, and Criteo’s agency partner program — rebranded as the Criteo Partner Program in late 2025 — offers white-label reporting dashboards and shared audience segments for agency clients. Brian Gleason, Criteo’s Chief Revenue Officer, stated at Shoptalk Spring 2026 that mid-market brands spending between $10K and $75K monthly now represent the platform’s fastest-growing revenue cohort, outpacing enterprise growth for the first time.

“We’ve deliberately built access paths for brands that Amazon DSP simply prices out. A $15K monthly budget can now get meaningful reach across 225 retail environments. That’s a structural advantage for the DTC middle market.” — Brian Gleason, Chief Revenue Officer, Criteo

Which platform delivers better ROAS for off-Amazon brands?

For brands primarily sold on Amazon, DSP’s closed-loop attribution consistently delivers reported ROAS between 4x and 9x for mid-funnel campaigns, according to agency benchmarks published by Tinuiti in April 2026. But those numbers collapse for brands using DSP to drive traffic to Shopify or other external destinations — Amazon’s conversion pixel has known reliability gaps outside its own ecosystem, and Amazon’s Terms of Service historically discouraged deep off-platform measurement integrations until its expanded AMC connector launched in February 2026.

Criteo Commerce Max’s reported ROAS for open-web retargeting campaigns averages 3.8x to 6.2x based on internal benchmarks Criteo shared at its Commerce Media Summit in May 2026. Those numbers are measured against retailer confirmation data — actual checkouts at partner retailers — rather than click-through proxies, which makes the comparison more apples-to-apples than most open-web DSP benchmarks. Several agency leaders who spoke to Ecommerce Times on background noted that Criteo’s ROAS figures are more defensible in client reporting because the attribution methodology is more transparent than Amazon’s black-box AMC outputs.

Which platform should agency leaders recommend in 2026?

The honest answer is that the two platforms address different distribution realities, and the most sophisticated agency programs are running both. Tinuiti, Dept, and Wpromote have all published case studies in Q1 and Q2 2026 showing that using Amazon DSP for upper-funnel awareness with Prime audiences — then recapturing lost browsers via Criteo Commerce Max on the open web — produces blended ROAS 22% higher than either platform in isolation.

But for operators who must choose one: if more than 60% of your GMV flows through Amazon, DSP’s attribution loop and Prime audience density are hard to beat. If you’re a Shopify-first brand selling across retail channels, Criteo Commerce Max’s cross-retailer signal graph and lower entry cost make it the more defensible choice. Brands like Ridge Wallet and Outer have reportedly piloted Criteo Commerce Max specifically because their Shopify storefronts represent the majority of unit volume, making Amazon DSP’s attribution model structurally misaligned with their reporting needs.

“The brands getting hurt right now are the ones treating DSP and Commerce Max as interchangeable. They’re not. One is an Amazon monetization tool. The other is a cross-retail media network. Knowing the difference is half the strategy.” — Marcus Ellerby, Head of Retail Media, Dept Agency

For marketplace operators and DTC founders entering the second half of 2026 with tightening ad budgets, the decision framework is straightforward: audit where your SKUs actually convert, match your measurement infrastructure to your distribution reality, and demand transparency on attribution methodology from both platforms before committing budget. The retail media war is producing better tooling for buyers — but only if you ask the right questions before signing the IO.
